Comment(by lftabera):
The patch applies to 4.6 after rebasing #8456
In my computer, from a first running (disc access is necessary), Sage
passes from 12.059 seconds to 11.290 So, a save less than 10%
If I further lazy import doing a
lazy import for every * imports and running
sage.misc.lazy_import.save_cache_file() the time drops to 10.259
If I run Sage with the initialitation files in RAM (disc acces is not
necessary) the time with lazy_importing all * drops from 1.123 to 0.907
So, still, with lazy imports, disc access is too high.
with Robert patch I get the following doctest failures:
